This relationship is often beneficial due to the fact the regular optimum allowable chain wear elongation of 3% is only legitimate for a maximum of 67 teeth in the large sprocket. Dress in need to be limited to around 1.5% for drives with a mounted center length, chains running in parallel, or drives that call for a smoother operation.
